[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a bimetal thermal protector calibration machine, which includes a calibration frame 1 and an automatic blanking conveying device. The automatic blanking conveying device includes a conveyor belt 12, two heating plates 13, a conical automatic blanking hopper 14 and a material guiding sliding frame 15. The conveyor belt 12 is installed on the top of the calibration frame 1. Both heating plates 13 are fixedly installed on the top of the calibration frame 1. The two heating plates 13 are respectively located on the front and rear sides of the conveyor belt 12. The conical automatic blanking hopper 14 is fixedly installed on the top of the calibration frame 1. The material guiding sliding frame 15 is fixedly installed on the top of the calibration frame 1. A vertical blanking port 16 is opened at the bottom of the material guiding sliding frame 15.

[0025] After the staff puts the material into the inside of the conical automatic blanking hopper 14, the material is automatically conveyed to the inside of the material guiding sliding frame 15 through the conical automatic blanking hopper 14. Since the material guiding sliding frame 15 is an inclined structure, the material can automatically slide downward inside the material guiding sliding frame 15. When the material slides to the position of the vertical blanking port 16, the material can automatically fall downward to the middle position of the conveyor belt 12 under the action of its own gravity, and the conveyor belt 12 conveys the material gradually to the right side, and the two heating plates 13 heat the material. At this time, by guiding the material through the material guiding sliding frame 15, it can be ensured that the material is placed at the middle position of the conveyor belt 12 each time. The conveyor belt 12 can prevent the material from contacting the heating plates 13 on both sides during the process of conveying the material, so that the material is in the center position of the two heating plates 13, making the material heat more evenly, thereby improving the heating effect of the material.

[0026] The bottom wall of the calibration frame 1 is fixedly connected with a storage box 2. The top of the storage box 2 is provided with a defective product storage groove 3 and a qualified product storage groove 4. The top of the calibration frame 1 is provided with a defective product blanking port 5 and a qualified product blanking port 6. The defective product blanking port 5 and the qualified product blanking port 6 are vertically corresponding to the defective product storage groove 3 and the qualified product storage groove 4. The top wall of the calibration frame 1 is slidably connected with a sliding plate 7. The surface of the sliding plate 7 is slidably connected with the inside of the qualified product blanking port 6. The top wall of the calibration frame 1 is fixedly installed with a cylinder 8. The output end of the cylinder 8 is fixedly connected to the surface of the sliding plate 7. The top of the calibration frame 1 is fixedly installed with an electric telescopic rod 9. The output shaft of the electric telescopic rod 9 is fixedly connected with a moving frame 10. The moving frame 10 is slidably installed on the top of the calibration frame 1. The top of the calibration frame 1 is fixedly installed with a temperature field 11.

[0027] The conveyor belt 12 gradually conveys the materials to the rightmost side and causes the materials to fall into the interior of the movable frame 10. At this time, the electric telescopic rod 9 is activated and drives the movable frame 10 to slide backward. When the movable frame 10 slides backward, it can drive the materials inside to move backward into the interior of the temperature field 11 for temperature inspection, mainly to check the compliance of the temperature. At this time, the materials are placed on the top of the slide plate 7. When the materials are qualified products, the air cylinder 8 can be activated and drive the slide plate 7 to slide to the left. At this time, the materials can automatically fall downward into the interior of the qualified product storage tank 4. When the materials are unqualified, the electric telescopic rod 9 can drive the movable frame 10 to continue sliding backward and drive the materials inside to move to the position of the defective product discharge opening 5. At this time, the materials can automatically fall downward into the interior of the defective product storage tank 3 by their own gravity, thus completing the automatic selection of qualified materials.

[0028] Working principle: For this bimetallic thermal protector calibration machine, the conical automatic feeding hopper 14 automatically conveys the materials into the interior of the material guiding slide frame 15. When the materials slide to the position of the vertical feeding opening 16, the materials can automatically fall downward to the middle position of the conveyor belt 12 by their own gravity, and the conveyor belt 12 conveys the materials gradually to the right side, and the two heating plates 13 heat the materials to make the materials heat more evenly. The conveyor belt 12 gradually conveys the materials to the rightmost side and causes the materials to fall into the interior of the movable frame 10. At this time, the electric telescopic rod 9 is activated and drives the movable frame 10 to slide backward. When the movable frame 10 slides backward, it can drive the materials inside to move backward into the interior of the temperature field 11 for temperature inspection. When the materials are qualified products, the air cylinder 8 can be activated and drive the slide plate 7 to slide to the left. At this time, the materials can automatically fall downward into the interior of the qualified product storage tank 4. When the materials are unqualified, the electric telescopic rod 9 can drive the movable frame 10 to continue sliding backward and drive the materials inside to move to the position of the defective product discharge opening 5 and fall into the interior of the defective product storage tank 3, thus completing the automatic selection of qualified materials.

[0029] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
